I run this short protocol (see below) using a Zeiss CZI stack , three channels about 1 GB (Icy memory 15000 MB). With ICY version 1.9 this protocol work very well in few seconds while with version 2.0.2 this protocol block on step 4 intensity properties (I tried with virtual dub ON/off).
Do you know where is the problem?
Thank for your help.

Sorry, I forgot, It takes > 11 minutes to complete version 2.0.2.

Indeed we were able to reproduce it and the speed difference is huge to say the least !
We will investigate and try to fix that asap (probably related to the intensity projection plugin which has been updated to be compatible with the new cache engine). Thanks for reporting !

We just updated the Intensity Projection plugin to improve the performance.
Still it remains a magnitude order slower than Icy < 2.0 version because we had to change the algorithm to make it compatible with the new virtual mode of Icy (which mean that you can compute intensity projection for a Z stack larger than your available memory).
On my test image:
* Icy < 2.0 version was computing projection in 0.4 second
* previous Icy >= 2.0 version was computing projection in ~100 seconds (!!)
* new Icy >= 2.0 version computed projection in 4 seconds
So unfortunately it remains much slower than older versions but probably acceptable compared to what you had just before.

You are right I confirm, the same stack version 2.0.2 intensity plugin 1.63 running time =135 sec, version 1.9 plugin version 1.53 =12 sec, same conclusion as you did.
Thanks a lot.
